Just an idea. Wilton Daisy Molds with 4" inch sticks (I also did some 6" sticks from the pretzel molds). 2" terracotta pots with all green M & M's as "grass". Wrap Saran Wrap around the styrofoam inserts before inserting.
Sorry; this idea would make more sense if I could post my pics. A little premature in posting here. Other members are helping me get my pics up.
I would love to see a pic. It sounds really cute.
I did similar rose favors for my 6year old's birthday this year. 2" terra pots, painted white, with each girl's name on the rim, brown M&Ms (for dirt) and rose lollipops. I didn't even need the styrofoam as I just pushed the pop through the M&Ms and into the hole in the bottom of the pot. They were a big hit!
